oil issue with turbo i have a rear mount turbo setup and im having an oil issue seems like after every time i stop the engine and then start it back up im blowing oil out the exhaust and the intake side of turbo my pump is pumping while running the car im thinking oil thats left in the feed and return might be seeping in the turbo after every shut down and thats causing my problem plus when i check for oil flow on my pump while car is running its not a steady flow its spurts of oil can anybody give me a suggestion on a fix
Thats a common problem with rear mount turbos is the oil pooling in the turbo, one easy way to fix that is to connect your oil scavenging pump to a turbo timer and let it run for a minute after shutoff. Also a check valve just before the turbo to keep the oil in the high pressure side from trying to equalize in the CHRA just from gravity.
I am about to build a rear mount in my swapped Tacoma and have been reading and researching like crazy, feel like an expert at this point, lol. I have built tons of front mount systems, but this will be my first rearmount setup, should be fun in a little 500hp Toyota Tacoma!
On the pump not being steady it sounds like your pump is outrunning what your turbo is expelling

Also, you might want to look into an oil restrictor in the feed line. Do some searching in the FI forum and you'll find a few threads.
